- Add a new Area to the project. This will be the breach area.
- Draw the breach area in the 3D world, in the location where the water from the breach should emerge (see tips below in gallery).
- Add an Attribute to the created Area, with the breach height attribute name and a height value.
- Open the Overlay's wizard.
- Continue to the step concerning breaches.
- Set the values of external area, external water level, and external surface level.
- The configuration wizard of the Flooding Overlay can now be closed.
It is best to draw the breach area not too close to the water body. Also, the breach area does not have to cover the whole levee, but only the slope of the levee on the side of the area that is going to inundate.
Select the external option in the wizard and fill in the external water level, surface level and area.
Notes
Currently, it is only feasible to create a breach with an external area via the configuration wizard, requiring the Flooding overlay specifically.
If the Water Overlay you are adding the breach to has a changed key for the breach height (or any other attributes of the breach), make sure that the Attribute you add to the Area has the name the key is set to.

For an example of the external breach area, take a look at the Testbed Water Module project available in all domains.
